Answer:
f(- 7) = 0
Step-by-step explanation:
Substitute x = - 7 into f(x) , that is
f(- 7) = 2(- 7 - 5)(- 7 + 7)
= 2 × - 12 × 0

x² = 1
x² - 1 = 0
Degree of quadratic equation should be 2.
2) 'a'- coefficient of x² cannot be 0
option a
3) option c
Standard form: ax² + bx +c = 0
4) c = 5
3x² + 8x = -5
3x² + 8x + 5 = 0
option c
5) b= 0

The Student Council is selling raffle tickets to raise money for the Winter Dance. They have a total of 275 tickets to sell and are told they must sell at least 82% of them to raise enough money. How many do they need to sell?
Answer:
226
Step-by-step explanation:
To find the percentage of a given value, firstly convert to a decimal by dividing by 100:
82 ÷ 100 = 0.82
Now, multiply this decimal by the number of tickets:
275 x 0.82 = 225.5
Because you can't sell half a ticket, round up.
This means the total of tickets they need to sell is 226.
Hope this helps!

Answer:
[tex]\sqrt[3]{\frac{1}{12} }[/tex] * n
Step-by-step explanation:
You want to get the n alone. In order to do that, you need to get rid of the 3rd power. The opposite of a power is a radical. So do:
[tex]\sqrt[3]{\frac{1}{12} }[/tex] * [tex]\sqrt[3]{n^3}[/tex]
This cancels out the n and turns the problem into:
[tex]\sqrt[3]{\frac{1}{12} }[/tex] * [tex]n[/tex]
I can't solve for n since I haven't been given the entire problem (what they're equal to), but you can solve for [tex]\sqrt[3]{\frac{1}{12} }[/tex].
